Section Abort
Messages
Section Abort is a function enabled in the program Header. When it is on, Section Abort
stops the program execution if failures are encountered early in the test. Failures in early
sections can produce false readings in subsequent sections, or, in the case of a short, could
result in damage to the board if DUT power is turned on. When Section Abort is off, the test
will continue running to the end despite failures during execution.
Below is an example of a screen message which may be displayed when Section Abort is
enabled:
Conts
367 to 383 Failed
Ignores
Shorts
Test terminated, Interconnect problem!
Test COMPLETED - FAILED!
When Section Abort is off, the following type of message is output to the screen:
Conts
Open 327 to 343
C 17 47 pF
Node 45
+12 Volt Power
Node 18
Digital
Bus 23 Stuck LOW
CRC 0000 NODE 200 PIN 1
CRC 0000 NODE 201 PIN 2
CRC 0000 NODE 202 PIN 3
Mixed mode test for DAC0802
Test terminated, Interconnect problem!
Test terminated, Analog problem
Test terminated, Power problem!
Test COMPLETED - FAILED!
The three test termination messages indicate that test execution continued to the end of the
program despite several failures in process.
Shorts Locator
Messages Shorts Locator provides more information about shorts than the standard shorts message,
which lists only the shorted nodes.
Shorts Locator provides a correlation between the physical parts of the board and the tester
node numbers. It helps you identify where to look for the short when you are repairing the
board.
Shorts Locator lists the devices connected to the shorted node, to the depth specified in the
Shorts ID Depth field under the Program Header Edit menu. The range of the field is 0–31.
The depth indicates how many device pins will appear. The maximum number of device
pins is 31.
